About The Position

The OT Security Engineer is responsible for securing the manufacturing Operational Technology (OT) environments across ~25+ segmented sites. This role provides hands‑on integration/network connectivity support, security monitoring, architectural guidance, and configuration expertise for complex shop‑floor networks.
As manufacturing sites continue expanding—including integration of new facilities and M&A-driven growth—this role ensures secure connectivity, asset visibility, and resilience of production‑critical systems. The OT Security Engineer will partner closely with IT Security, Network Engineering, Manufacturing Systems, site leadership, and shop‑floor teams to protect production operations from cyber threats and support secure, reliable OT environments.

Requirements

• 5+ years of experience in OT, industrial control systems (ICS), or manufacturing network security support.
• Strong understanding of OT networking (Layer 2/3), industrial protocols (Modbus, OPC-UA, BACnet, Ethernet/IP, PROFINET), and segmented architectures.
• Hands‑on experience troubleshooting multi‑subnet network environments.
• Familiarity with security monitoring platforms for ICS/OT environments.
• Experience working in or supporting manufacturing or industrial production facilities.
• Ability to communicate complex technical issues clearly to both technical and non‑technical stakeholders.

Nice To Haves

• Experience with network segmentation design and firewall rule creation for OT systems.
• Prior involvement with shop‑floor system integrations, PLC/HMI/SCADA environments, or MES technologies.
• Familiarity with NIST 800‑82, ISA/IEC‑62443, or similar OT security frameworks.
• Experience supporting OT environments through acquisitions or facility expansions.

Responsibilities

• Provide day-to-day security engineering, monitoring, and integration/network connectivity support for network‑segmented OT environments.
• Support the continued rollout, maintenance, and optimization of OT network segmentation across all manufacturing facilities.
• Evaluate and enhance security controls that protect production operations, including anomaly detection, access control, and incident response readiness.
• Serve as a subject matter expert for OT systems, ensuring secure configuration of industrial subnets, interfaces, and connectivity required for manufacturing equipment and processes.
• Improve visibility into OT assets, vulnerabilities, and shop‑floor network activity.
• Strengthen alignment between OT operations and corporate IT Security policies, standards, and risk management practices.
• Provide integration/network connectivity support for segmented OT networks across all manufacturing facilities, including remote and onsite assistance.
• Troubleshoot connectivity issues between OT subnets, devices, and required corporate systems without disrupting production.
• Support ongoing network reconfiguration needs in complex environments (e.g., multi‑subnet shop‑floor architectures).
• Assist with recovery efforts during OT-impacting events or cyber incidents.
• Monitor OT environments using enterprise-approved tools for anomaly detection, threat monitoring, and asset inventory.
• Analyze alerts and logs from OT security platforms; assist in investigation and response.
• Maintain and enhance security visibility across shop‑floor environments.
• Partner with Network Engineering on OT segmentation design, firewall policies, and secure connectivity patterns.
• Validate architecture for new manufacturing sites, expansions, and M&A integrations.
• Ensure secure and compliant configuration of PLCs, HMIs, SCADA components, and shop‑floor servers where applicable.
• Support implementation of OT security governance, including access control and secure remote access.
• Support ingestion of OT asset inventory collection into OT security tools.
• Identify and track end-of-life devices, unsupported operating systems, and high‑risk components.
• Work with plant engineering teams to remediate vulnerabilities where feasible with minimal business disruption.
• Assist in rollout of OT security policies, awareness training, and standards across the manufacturing network.
• Support audits, compliance initiatives, and documentation of architecture, configurations, and segmentation boundaries.
• Participate in security reviews for OT system upgrades and technology evaluations.

Benefits

• Generous and flexible paid time off including paid personal time off, caregiver, parental, and volunteer leave
• Competitive health insurance plans and 401(k) match, with benefits starting day one
• Competitive and performance-based compensation packages and bonus plans
• Educational assistance, leadership development programs, and recognition programs
